Homework 2instructionsselection Statementsin This Homework You Will D

In this homework, you will design a program to perform the following task: Calculate the total price to purchase all the components required to build a state-of-the-art gaming computer from components available on the internet. Your analysis should include research on prices and options for various components, assuming the computer will have specific components such as CPU, case, power supply, motherboard, hard drive, RAM, DVD drive, sound card, monitor, graphics card, and operating system. Limit options for some components to three choices to maintain manageable complexity.

You should clearly document your problem analysis, including the necessary input, output, formulas, and sample calculations. Additionally, develop the program design with pseudocode for the main module and submodules, following modular programming principles. Prepare a hierarchy chart illustrating module relationships, and list pseudocode for each module with header and step comments.

Finally, create a test plan with at least 5 data sets, each including expected output, to validate your program's correctness.

Paper For Above instruction

Building a state-of-the-art gaming computer involves careful selection of various components, each with distinct costs and options. Designing a program to accurately compute the total purchase price requires systematic analysis of component choices, their prices, and the structure of the program itself. This process encompasses problem analysis, program design, pseudocode development, and testing, all aimed at creating an efficient, modular, and reliable calculator.

Problem Analysis

The objective is to calculate the total cost of building a gaming computer based on user-selected components. The primary inputs include the choices for each component, such as CPU, case, power supply, motherboard, hard drive, RAM, DVD drive, sound card, monitor, graphics card, and operating system. For simplicity, each component can have three options, each associated with a specific cost, to limit program complexity and facilitate user interaction.

The output will be the total price, computed as the sum of base component costs, plus fixed fees such as shipping and dealer charges. The input data can be collected via user prompts, and the output displayed on the screen, showing the total cost with a breakdown if desired.

The formulas involve summing individual component costs plus fixed additional charges:

Total Price = Sum of component costs + Shipping fee + Dealer fee

For example, if the selected components are assigned costs as follows:

- CPU: $300

- Case: $100

- Power supply: $80

- Motherboard: $150

- Hard Drive: $200

- RAM: $80

- DVD drive: $50

- Sound card: $70

- Monitor: $250

- Graphics card: $400

- Operating System: $120

Then, total cost = sum of all above + $500 shipping + $175 dealer charge.

Program Design

The program implementation should be modular, consisting of a main module and several submodules, each responsible for a specific task. The main module will handle initial input and coordination, calling submodules to process options and display the final total.

The main module’s responsibilities include:

- Displaying a welcome message

- Collecting general input if needed

- Calling submodules for each component to obtain costs

- Calculating the total sum

- Displaying the final price

Each submodule will:

- Present options for one component

- Accept user input

- Map input to component cost

- Return the cost to the main module

The hierarchy chart illustrates the structure:

• Main Module

     - Submodule: Get CPU Cost

     - Submodule: Get Case Cost

     - Submodule: Get Power Supply Cost

     - Submodule: Get Motherboard Cost

     - Submodule: Get Hard Drive Cost

     - Submodule: Get RAM Cost

     - Submodule: Get DVD Drive Cost

     - Submodule: Get Sound Card Cost

     - Submodule: Get Monitor Cost

     - Submodule: Get Graphics Card Cost

     - Submodule: Get OS Choice Cost

     - Final calculation and display

Pseudocode template for Main module:

/ Main Module Pseudocode /
declare variables for each component cost
display welcome message
// Collect component choices via submodules
cpuCost = Get_CPU_Cost()
caseCost = Get_Case_Cost()
powerSupplyCost = Get_Power_Supply_Cost()
motherboardCost = Get_Motherboard_Cost()
hardDriveCost = Get_Hard_Drive_Cost()
ramCost = Get_RAM_Cost()
dvdCost = Get_DVD_Drive_Cost()
soundCardCost = Get_Sound_Card_Cost()
monitorCost = Get_Monitor_Cost()
graphicsCardCost = Get_Graphics_Card_Cost()
osCost = Get_OS_Cost()
// Calculate total
totalPrice = cpuCost + caseCost + powerSupplyCost + motherboardCost +
hardDriveCost + ramCost + dvdCost + soundCardCost + 
monitorCost + graphicsCardCost + osCost + shippingFee + dealerFee
// Display total
Display "The total price for your gaming computer is: $" + totalPrice

Each submodule follows similar pseudocode, e.g., for CPU selection:

/ Get_CPU_Cost /
display CPU options with codes and prices
input user selection
map selection to cost
return cost

Test Data and Validation

Prepare at least five sets of input data representing different configurations, and note the expected total prices. This testing ensures the program correctly handles various choices and sums costs accurately. Use input combinations such as:

Verifying these results against manual calculations confirms the correctness of implementation.
